Definitions

  • the invention relates to a rolling device with an adjusting device, in particular for adjusting a horizontal offset of a roller of the rolling device, in particular according to the preamble of claim 1, see for example JP-A 06269818 ,
  • Rolling or rolling mills are well known in the art.
  • rolling mills are known in which a horizontal offset rate of a work roll is made relative to the adjacent support rollers as horizontal stabilization. This is particularly necessary if you want to run different stitch programs with the rolling device.
  • adjusting transmission elements for adjustment hydraulic cylinder and wedge adjustments by means of a movable wedge. Adjustments with wedges are for example by the DE 17 770 54 A known.
  • the EP 0 154 896 B1 discloses both hydraulic cylinders and mechanical adjusting gears.
  • the object is achieved by a rolling device with the features of claim 1.
  • two opposing adjusting devices are provided at each end of the roller.
  • the adjusting device has two pressure chambers for pressurizing the piston, wherein in each case a space on the respective opposite sides of the piston are arranged.
  • the position of the piston can be set or controlled safely.
  • a piston rod connected to the piston via a lever arrangement acts on the roller directly or indirectly in the adjustment direction of the roller, the piston being parallel to the roller axis is adjusted and the at least one lever of the lever arrangement causes the adjustment of the roller perpendicular to the roll axis.
  • the position of the piston can be detected by means of a sensor. It is expedient if the sensor is integrated in the housing of the adjusting device or is connected thereto, as in particular is mounted on this from the outside. In this case, the position of the sensor can advantageously not be lost because the sensor can be directly connected to the displaceable element of the piston-cylinder unit or to the elements which can be displaced relative to one another.
  • FIG. 1 schematically shows a view of a rolling device 1 with a framework 2, such as rolling stand, with four stud posts 2a, 2b, 2c, 2d, and arranged in the space between the stud posts 2a, 2b, 2c, 2d Work roll 3, which is stored stored in roller bearings or work roll bending blocks 4. Adjusting devices 5 are provided between the uprights 2 a, 2 b, 2 c, 2 d of the framework 2 and the roller bearings or work roll bending blocks or displacement blocks 4 in order to displace the roller or the work roll 3 in the direction 6 perpendicular to the axial direction 7 of the roller.
  • the roller 3 is stored mounted on a chock 8.
  • the adjusting devices 5 thus serve for horizontal adjustment of the roller 3 in a direction perpendicular to the axis of the roller third
  • the adjusting devices 5 are arranged such that they drive an adjustment movement in the direction of the arrow 6 perpendicular to the axis 7.
  • the adjusting device 10 is formed by a pressure medium actuator, such as a hydraulic actuator 11, as in FIG. 2 is shown.
  • a pressure chamber 25 is formed between the component 23 and the component 18.
  • a pressure medium can be admitted or pressurized, so that the two components 23 and 18 are impelled away from each other and move accordingly away from each other or that they move towards each other.
  • a piston 14 is received in a cylinder chamber 15,16, so that two druckstoffbeetzschlagbare cylinder or chambers 15,16 are formed, wherein the spaces 15 and 16 are each arranged on one side of the piston 14, so that a pressurization of the space 15th the piston 14 is acted upon in the direction of roller and a pressurization of the space 16, the piston 14 is acted upon in the direction away from the roller.
  • a holding device or adjusting device is created, which is formed as a retaining cylinder and which also serves to withdraw the elements 20,21 and 23.
  • the space area 15, 16 is formed in a housing 17, which is connected to the stud post 12.
  • the housing 17 is formed in two parts and constructed from the two sub-housings 18,19.
  • the piston is received with its piston body in the housing 17 and protrudes with a piston rod through an opening in the housing part 18, where it is connected to the roller bearing 20.
  • an intermediate element 21 may be provided which allows a guide in the direction perpendicular to the direction of movement of the adjusting device and perpendicular to the roll axis.
  • the cylinder of the space portion 25 is formed by the elements 23, 18 and is received in a recess of the block 17.
  • a sensor 22 which detects the position of the actuated by the cylinder 25 element 23 directly or indirectly.
  • the sensor 22 on a pin 24, which is supported on the element 21 or with the associated element 23.
  • Particularly advantageous in this embodiment is the good controllability of the position by the pressurizable spaces or cylinders 25 and / or 15,16, so that the position of the element 23 and / or the piston 14 can be adjusted at any time clearly and thus the position of the roller 13. Furthermore, the execution according to FIG. 2 constructed particularly compact, since the hydraulic unit with piston / cylinder unit 25 acts directly on the roller 3.
  • the adjusting device 30 is formed by a pressure medium actuator, such as a hydraulic actuator 31, which acts on the roller 3 via a lever arrangement 32, such as he in FIG. 3 is shown.
  • a pressure medium actuator such as a hydraulic actuator 31, which acts on the roller 3 via a lever arrangement 32, such as he in FIG. 3 is shown.
  • the hydraulic actuator 31 is arranged such that the piston 34 is accommodated in a cylinder space 35, 36 and forms two pressure-medium-loadable spaces 35, 36, the spaces 35 and 36 being arranged on one side of the piston 34, respectively so that pressurization of the space 35 moves the piston 34 to the right, and pressurization of the space 36 moves the piston 34 to the left.
  • the space portion 35,36 is formed in a housing 37 which is connected to a housing 38 which receives the lever assembly 32, which in turn is attached to the stud post 33.
  • the housing 37 is formed in two parts and constructed of the two sub-housings 39,40, where in the part 39 is pot-shaped and the part 40 is formed in the manner of a flange.
  • the flange 40 in this case has an opening through which the piston rod 41 protrudes in order to displace the roller 3 via the lever arrangement 32. In the region of the opening of the flange 40, a seal 42 is further provided.
  • the piston rod 41 is connected to an axially displaceable rod 43, which is formed with a hinge 44 to which a lever arm 45 is hingedly connected.
  • the lever arm is articulated via a further joint 46 with the element 21.
  • This part 21 is in turn connected to the roller bearing 20, so that a displacement of the element 21 is transmitted directly to the roller 3.
  • the piston rod 41 Upon a displacement of the piston 34 due to a pressurization of the pressure chambers 35 and / or 36, the piston rod 41 is displaced and adjusted to a predeterminable position. Thereby, the rod, such as push rod, axially displaced and thus the joint 44. Since the roller bearing 20 is formed substantially immovable in the direction of the roll axis, changes the position of the lever arm 45 in its angular position by the displacement of the pivot point 44 Axis of the roller or considered to a perpendicular thereto, and thus the distance between the stator 33 and the roller is defined and adjusted. Thus, the roller bearings are substantially immovable in the direction parallel to the roll axis, they are locked with the guides 47, which allow only a movement in the direction perpendicular to the roll axis.
  • a sensor 48 is furthermore provided, which detects the position of the piston by means of a sensor 49.
  • an opening is provided at the head of the housing 39 through which the sensor 49 of the sensor 48 can pass and engage in an opening or bore of the piston.
  • roller 4 Roller bearing, roll bending block 5 adjustment 6 Direction of the adjustment 7 Axial direction, axis 10 adjustment 11 Druckschaktuator 12 stand post 13 roller 14 piston 15 Cylinder room, pressure room 16 Cylinder room, pressure room 17 casing 18 Enclosures 19 Enclosures 20 Roller bearing, roll bending block 21 intermediate element 22 sensor 23 Connected element 24 pen 25 Cylinder, pressure chamber 30 adjustment 31 hydraulic actuator 32 lever assembly 33 stand post 34 piston 35 Cylinder room, pressure room 36 Cylinder room, pressure room 37 casing 38 casing 39 Enclosures 40 Part housing, flange 41 piston rod 42 seal 43 pole 44 joint 45 lever arm 46 joint 47 guide 48 sensor 49 sensor
